To all whom 'it may concern:

Be it known that I, FERDINAND R.W0LTER,

a citizen of the United States, residing at' Minneapolis, in the countyof Hennepin and i o State of Minnesota, have invented certain new anduseful Improvements in Mop- Holders; and I do hereby declare thefollowing to be a full, clear, and exact descrlptlon of the invention,such as will enable others skilled in the art tol which it- Aap'pertainsto make and use the same.

My invention has for its object to provide an improved mop-head, theterm mop-head being. used -in a broad sense to -include de# vicesadapted to hold mop rags, floorand window Scrapers, andthe like. l

Generally stated, the invention conslsts of the novel devices andcombinations of d evices hereinafter described and defined 1n theclaims.

In the\ accompanying drawings whlch illustrate the invention in itspreferred form, like characters indicate .like parts throughout theseveral views. u

Referring to the drawings, Figure 1 1s a plan view of the improvedmop-head, wlth some parts broken away, and some. arts sectioned; Fig. 2is a side elevation o the parts shown in Fig. 1, some portions beingbroken away; Fig. 3 is a fragmentary view partly in-plan and partly in.section on the line fr ma of Fig. 2; Fig. 4 is a detail in elevation,with parts broken away showing the relatively movable clamping bar ofthe mophead; Fig. 5 is a detail in transverse section taken on the line:v5 of Fig. 1 and Fig. 6 is a transverse section taken on the line ai w?of Fig. 1. I

The numeral 1 indicates a pole, to one end of which a cast socket-or cap2 is rigidly secured in any suitable way. The soc et 2 is provided witha fork made up, preferably, of a pair of stiff metal rods 3, theconverging ends of which'are cast, or otherwise rigidly secured in oneend of the said socket 2, and the outer ends of which are bent inward ortoward each other to form hook-like .projections to fingers 4.

The mop cloth or scraper blade is adapted to be clamped and held betweenrelatively fixed and relatively movable clamping bars 5 and 6,respectively, both of which, as shown, are channel-shaped in crosssection, the channel of the bar 6 being large enough to receive thechannel bar 5. The channel bar 5 is preferably a stamped metal piececloth or rag of bul provided in its channel near its ends withdepressions or bulged seats 7 which are normally engaged by the hookends 4 of the fork rods 3. This affords one extremely simple and eicientway of detachably connecting the bar 5 to the fork rods 3. Theimportance of thisdetachable feature will be later noted.

The relatively movable clamping bar 6 is preferably-a cast part having acentrally located stem portion 8cast integrally therewith, and formedwith diametrically opposite longitudinally extended ribs ,9. This stem 8is guided by, and movable endwise, in a guide tube 10, the other en d ofwhich is rigidly seated in the cap. 2, being preferably cast therein.This guide tube 10 is provided with long diametrlcally oppositelongitudinally extended slotsl 10l in which the ribs 9 of the stem 8 arearranged to work.` In its extreme end, the said stem 8 is provided witha depression 8 .that is engaged by an approximately spherical head 11 ofa clamping lever 12 and which lever has a curved cam acting section 12that Work's through es i' the slots 10" and bears also against the roundhead of a plunger- 13. This plunger 13 affordsl a yielding abutmentagainst which the said lever acts, and it is spring-pressed by a quitestrong coiled spring 14 seated in the guide tube 10, and re-acts againstthe cap 2. As the head 11 is wider than the slots 10, it affords asliding pivotal connection between the said lever and the tube 10, whichprevents the lever from being accidentally disconnected from the tube.As the head 11 rest-s in the depression 8 of the stem8, and this, inturn, bears against the wallsof the guide tube 10, italords additionalsu port or the head 11 so that these parts will readily wear. out. Bythe construction employed, it obviates the necessity of weakenlng thetube 10 by any bolt or rivet holes,

and renders the clamping' lever 12 readily` not when the mop-head isused to clamp a mop form, and which cannot be easily applic between theclamping bars of an ordinary mop-head, or easily re- .moved therefrom.vWith this barf madel de'- tachable, any lknd of a bulky rag or mopl'cloth may be easily applied between the cooperating clamp bars, orremoved from ,be-v tweenthe same when the-said bar 5'is detached from`the rods 3. When such mop' cloth Yor rag is` placed 'between the twoclamping bars 5 and 6, the former maybe quickly and easily ap lied inworking position, or detached. therwise stated, 'the feature of makingthe relatively fixed bar 5 removable is,l however, of 'greatestimportance because of the easy and ready means it. affords for puttingin and removing the mop 'cloth or rag (especially the latter fprocoundless) fromthemo -head. It has been in practice, that t e fabric, suchasis being used for this purpose, after continued use, will become badlysoiled andl tangled up'so that the removal from thefmop-head is'rendered a very tedious and unpleasant tas k or operation. l

` When the clamping lever 12is turned into the position indicated lbydotted lines in Fig. 1, the relatively movable clamp bar 6' may beretracted from the bar 5, as indicated 4 by dotted lines in said view.When, however, the said lever is turned into the position indicated byvfull lines in said Fig). 1, the two clamping bars 4willv be tig tlypressed toward each' other and will be caused totightly pinch and holdthe mop cloth. The yielding abutment 13, when or blades for cleaningoors, or in connection with smaller scraper blades Vor-other v cleaningdevices for cleaning windows.

In actual practice, the device has been found highly efficient, veryconvenient, and easily operated.' Furthermore, it `may be constructed atcomparatively small cost.

What I claim is: f

1. A mop-head comprising a member hav- .said detachable Y clamping bar.

ing diverglng prongs, Aa clamping bar havt ing degat-.btie "elgagemntwith' the'A said prongs a,` relatively movable clamping bar, and meansfor pressing the latter toward the 2.` A mop-head comprising a member.having projecting prongs, a clamping bar detachably engageable with theoset ends of said prongs, wrelatively movable clamping bar, and meansfor ressing' the latter toward the said detacha le clamping bar.

3.111 a mop-head, the combination'with a member having diverging prongsand a central guide tube,- of a pair of. coperating clamping bars,- oneremovably connected to 'said prongs. and theother yslidably mounted onsald guide tube, a'cam lever slidably pivotedto said guide tube andoperative on one of thel` said: clamping bars, and a yielding abutmentagainst which the said cam lever is arranged to act, substantially asdescribed.
